3 Trimming To cut off part of the seam allowance to reduce bulk. Trim away 3/8 inch of fabric along the full length of the seam.
4 GradingMeans to trim each layer of the seam allowance to a different width.Trimming the seam reduces bulk more smoothly.
5 Clipping Means to cut slits into the seam allowance. Needed on all seams with an inside curve.Usually done at ½ inch intervals at a 90°angle.
6 REASONS If seam lines tend to pucker or look bulky. Want seams on a finished garment to appear smooth.
7 Notching Means to cut wedges into the seam allowance. Is done on seams with an outside curve.Removes excess fabric that otherwise cause the seam to be bulky when turned.
8 Trimming-cut off part of the seam allowance to reduce bulk.
9 Method of Trimming-trim away ⅜ of an inch of fabric along the full length of the seam.-this will leave a ¼ inch seam allowance.
10 Grading -cutting layers of a seam allowance to varying (different) widths.
11 Method of Grading -trim each seam allowance to a different width -garment seam allowance is left widest-facing seam allowance is trimmednarrowest-layers in between, trimmed more than the garment, but less than the facing
12 Clipping -to cut slits into the seam allowance. -needed on all seams with an inside (inward) curve.
13 Purpose of clipping -seam will turn over smoothly. -curved seams not clipped, willpucker when turned.
14 Method of Clipping-use points of shears - cut into seam allowance at right angles to seam line-cuts should be ½” apart, cutting almost to the seam line.-inside corners clip diagonally from seam edge to stitching
15 Notching -cut wedges into the seam allowance. -needed on all seams with an outside (outward) curve.
16 Purpose of Notching-remove excess fabric – if not removed will cause the seam to be bulky when turned.
17 Method of Notching -v-shaped cuts (wedges) that are cut at ½” apart to the seam line.
18 Trimming Corners -corners are trimmed diagonally across the corner.
19 Method of Trimming-trim excess fabric from the sides of a point at an angle.
